Hints in the craters
Rampart Craters • These are unique to
Mars and are due to frost heaves from water trapped as ice in the Martian soil.

Another clue: Hematite
• This kind of hematite (an
iron ore) only forms in
water. This insinuates that
Mars had to have flowing
water at one point in order
to make it.
• This picture was taken by
one of the rovers on the
surface of Mars.
